Chapter 1 BFD Configuration Commands
1.1 BFD Configuration Commands
1.1.1 bfd authentication-mode
Syntax
bfd authentication-mode{md5 key-id key | sha1 key-id key | simple key-id
password }
undo bfd authentication-mode
View
Interface view
Parameters
md5: Uses message digest 5 (MD5) authentications.
sha1: Uses secure hash algorithm (SHA-1) authentication.
simple: Uses plaint text authentication.
key-id: Authentication key ID, in the range 1 to 255.
key: A string of 1 to 16 characters. It is displayed as a 24-byte cipher text string when
the display current-configuration command is executed.
password: Password, a string of 1 to 16 characters when the simple keyword is used. It
is displayed when the display current-configuration command is executed.
Description
Use the bfd authentication-mode command to configure the BFD authentication
mode and key on the interface.
Use the undo bfd authentication-mode command to remove the authentication mode
on the interface (only one authentication mode can be configured on an interface).
By default, no authentication is configured on an interface.

1-2
Note:
The authentication mode, key-id, key (or password) used by both ends trying to
establish a BFD session must be the same. If one end changes its authentication mode,
it sends the authentication packets in both the new and the old mode at the same time
until the other end also changes to the same authentication mode.
Examples
# Configure VLAN-interface 1 to support MD5 authentication, setting the authentication
key-id to 15 and authentication key to BfdKey.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface 1] bfd authentication-mode md5 15 BfdKey
1.1.2 bfd detect-multiplier
Syntax
bfd detect-multiplier value
undo bfd detect-multiplier
View
Interface view
Parameters
value: Maximum number of consecutive BFD control packets that the remote device
fails to receive from the local device interface before considering the BFD session down,
in the range of 3 to 50.
Description
Use the bfd detect-multiplier command to configure the maximum number of
consecutive BFD control packets that the remote device fails to receive from the local
device before considering the BFD session down.
Use the undo bfd detect-multiplier command to restore the default.
The default is 5.
Examples
# Configure the detect multiplier as 6 on VLAN-interface 1.

1.1.3 bfd echo-source-ip
Syntax
bfd echo-source-ip ip-address
undo bfd echo-source-ip
View
System view
Parameters
ip-address: Source IP address of BFD echo packets.
Description
Use the bfd echo-source-ip command to configure the source IP address of BFD
echo packets.
Use the undo bfd echo-source-ip command to remove the configured source IP
address of BFD echo packets.
Note that, since a large amount of ICMP redirect packets may be sent by the remote
device, causing network congestion, do not configure the source IP address of the BFD
echo packets to belong to the same network segment as any interface address of the
device.
Examples
# Configure the source IP address of BFD echo packets as 10.1.1.1.

Parameters
value: Minimum BFD echo receiving interval, in milliseconds. This value is in the range
of 200 to 1000 and defaults to 400.

1-4
Description
Use the bfd min-echo-receive-interval command to configure the minimum BFD
echo packet receiving interval on the interface.
Use the undo bfd min-echo-receive-interval command to restore the default.
The default value is 400 milliseconds.
Examples
# Configure the minimum BFD echo receiving interval on VLAN-interface 1 as 300
milliseconds.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface 1] bfd min-echo-receive-interval 300
1.1.5 bfd min-receive-interval
Syntax
bfd min-receive-interval value
undo bfd min-receive-interval
View
Interface view
Parameters
value: Minimum interval for receiving BFD control packets, in milliseconds. It is a
multiple of 100 milliseconds. It is in the range of 200 ms to 1000 ms and defaults to 400
ms.
Description
Use the bfd min-receive-interval command to configure the minimum interval for
receiving BFD control packets.
If the remote device sends BFD control packets at an interval smaller than the minimum
receiving interval of the local device, the remote device changes its sending interval to
the minimum receiving interval of the local device.
Use the undo bfd min-receive-interval command to restore the default.
By default, the minimum interval for receiving BFD control packets is 400 milliseconds.
Examples
# Configure the minimum interval for receiving BFD control packets on VLAN-interface
1 as 300 milliseconds.

View
Interface view
Parameters
value: Minimum interval for transmitting BFD control packets, in milliseconds. It is a
multiple of 100. It is in the range of 200 to 1000 and defaults to 400.
Description
Use the bfd min-transmit-interval command to configure the minimum interval for
transmitting BFD control packets.
The minimum interval for transmitting BFD control packets through an interface
ensures BFD control packets are not transmitted faster than the device can deal with.
The actual interval for transmitting BFD control packets at the local device should be
the greater between the minimum interval for sending BFD control packets configured
on the local interface and the minimum interval for receiving BFD control packets on the
remote device.
Use the undo bfd min-transmit-interval command to restore the default.
By default, the minimum BFD transmit interval is 400 milliseconds.
Examples
# Configure the minimum interval for transmitting BFD control packets on
VLAN-interface 1 as 300 milliseconds.

[Sysname] interface vlan-interface 1

View
System view
Parameters
active: Uses the active mode. In the active mode, upon being enabled with BFD, an
interface actively transmits a BFD control packet to the remote device.
passive: Uses the passive mode. In the passive mode, an interface does not actively
transmit a BFD control packet to the remote end; it transmits a BFD control packet only
after receiving a BFD control packet from the remote end.
Description
Use the bfd session init-mode command to configure the mode for establishing a
BFD session.
Use the undo bfd session init-mode command to restore the default. By default, BFD
sessions are established in the active mode.
Examples
# Configure the session establishment mode as passive.

[Sysname] bfd session init-mode passive
1.1.8 display bfd interface

interfaces.
Besides the information displayed by the display bfd interface command, the display
bfd interface verbose command displays brief session information of the interfaces.
